I feel it should be on the room owner, or whoever is in charge to monitor their customers instead of putting up demeaning signs. I could see some of those rules posted I guess, but I think when you see bad behavior, let them know your expectations.
Funny jumping is not mentioned. We have a friend that regularly comes over to play, and I don't allow jumping on my table. I get teased about it whenever I put her in a situation where she wants to use her jump cue, I just smile.
Chalking over the table just isn't worth saying anything. I'll just vacuum the next day after company leaves.
